create_flowMap: A Flow Map Creation Function

In andrewcberkley/EarthTimeR: Tools for formatting data and ingesting it into EarthTime

Description

This function creates a flow map from a dataframe. It will output a .json file in your working directory for you to later push to a specific EarthTime instance.

Usage

create_flowMap(
  dataframe,
  origin,
  destination,
  value_column,
  date_column,
  projected_coordinate_system = "epsg_3857",
  centroids_geojson = "country-centroids.geojson",
  centroids_json = "centroids_by_iso_alpha_3.json",
  output_dir = getwd()
)

Arguments

dataframe	Specify the name of the dataframe that you'd like to transform into a dot map .json file.
origin	Specify the column name (in quotes) that contains the latitudinal coordinates.
destination	Specify the column name (in quotes) that contains the longitudinal coordinates.
value_column	Specify the column name (in quotes) that contains the primary value being visualized.
date_column	Specify the column name (in quotes) that contains the date category.
projected_coordinate_system	A flat, two-dimensional representation of the Earth based on a sphere or spheroid geographic coordinate system, but it uses linear units of measure for coordinates, so that calculations of distance and area are easily done in terms of those same units. Defaults to EPSG:3857 (WGS 84 / Pseudo-Mercator) used for rendering maps in Spherical Mercator, Google Maps, OpenStreetMap, Bing, ArcGIS, ESRI, etc.
centroids_geojson	Defaults to "country-centroids.geojson" included with the package.
centroids_json	Defaults to "centroids_by_iso_alpha_3.json" included with the package.
output_dir	Output director for .json file. Defaults to current working directory.

Examples

## Not run: 
create_flowMap <-  function(dataframe, origin, destination, value_column, date_column)

## End(Not run)
